Most of the focus of Friday's physicality landed on tight end Martellus Bennett, but coach Marc Trestman was pleased with the physical play in the trenches.

BOURBONNAIS — Things got physical during a long day at Bears training camp. Weather pushed the practice back six hours, as head coach Marc Trestman said it was a “swimming pool” on the fields for the normal 9 a.m. start.

When things got underway in the humidity, Martellus Bennett certainly set the tone with several scuffles, but the play on the field before the whistle also allowed the Bears to show off some physicality.

“The effort was outstanding. Special-teams wise and in all phases that we practiced today, just excellent, highly competitive,” Trestman said.

All eyes are on Jay Cutler and how the new passing attack will look, but Matt Forte and Michael Bush will be very involved in the offense, and Trestman was pleased with the way both sides of the ball handled a large amount of run plays.

“I thought there was a lot of ebb and flow, especially in the run game, period. It was physical,” he said. “The defensive line would get great fits and make the stop, and then offensively, the guys had a chance to create some holes. We did a lot of work with our trapping and cutting game today — not cutting people — just moving guards and pulling people and things like that.”

The Bears also spent a lot of time in the red zone during Friday afternoon’s session, in part to save the players’ legs after a long day.

“We spent a lot of time [in the red zone], really to shorten the field and take a little bit off their legs and still got a lot accomplished in a highly competitive manner,” Trestman said.
